I have created a very simple document in Lyx and want to preview it. But the "View" action (the one bound to Command+R) and its corresponding tool bar button (with the icon showing two large eyes) are inactive/disabled. Strangely, "View other Format" is working fine, for example for PDF.
I am on Mac OS 10.9 with MacTex 2014 and Lyx 2.1.1 installed. I have already tried to re-compute my configuration (last item in "Tools" menu) and re-install Lyx but "View" remains disabled.
Many thanks in advance!
